MECHANISM FOR OOAL-BUNKERING'SHIPS.

SPECIFICATION forming part of Letters Patent No. 793,122, dated June 27, 1905.

To all whom it may concern.-

Be it known that I, JEREMIAH CAMPBELL, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Mechanism for Coal-Bunkering Ships, of which the following is a specification.

In bunkering a ship at sea prior to my invention a barge was provided carrying a tower in which the coal-hoisting apparatus was located, the barge itself being sometimes filled with coal or in other cases the cord-barge being drawn alongside ofit. Sometimes, also, the tower was on a barge separate and distinct from the power-barge, or if the bunkering was to be done near the wharf the engine was on the wharf and the tower on the barge. Vhere the tower is mounted upon a coalbarge, it must be made movable thereon in order that it may be drawn from one end of the barge to the other, according to the location of the coal-bunkers in the barge. As each bunker on the barge is emptied the tower must be relocated over a full bunker and the barge must be relocated with relation to the ship, so as to bring the tower in its new position on the barge alongside of the port through which the bunkering is being done. Asl have intimated above, heretofore two movements have been necessary, and these movements have required considerable time to effect and in a days work sometimes making serious delay. As heretofore practiced the barge had to be warped forward, for example, and when that operation was completed the tower had to be moved back, or vice versa.

My invention is intended to overcome this trouble; and it consists in means whereby the barge and tower are moved simultaneously, the barge being drawn in one direction and the tower in the other. For this purpose I provide a shaft carrying spools and capable of connection with an engine or other source of power. Supposing the spools to be four in number, as shown in the drawings, one spool carries the rope for warping the barge rearward, another spool for *arping the barge forward, a third spool for moving the tower rearward, and a fourth spool for moving the tower forward.

My invention will be understood by reference to the drawings, in which--- Figure 1 is a side elevation of a steamer and barge located in position to be operated in the manner above referred to and embodying my invention. Fig. 2 is a plan view showing a barge and a portion of a steamer. Fig. 3 is a side elevation of the barge, somewhat enlarged and less diagrammatic than the views shown in Figs. l and 2; and Fig. 4: is a plan of the barge.

A is the steamer, and B is the barge.

C is the tower, which may be constructed in any of the now well-known ways, this term being used to include a crane or the like, by means of which tackle is supported to operate a grab, the grab being shown at D. The tower C is mounted on a platform C, provided with suitable wheels (2, which run upon rails 6 on the barge B. The grab D is operated by means of hoisting and operating ropes (Z, which run from the grab in the usual way and over pulleys in the top of the tower and down around the pulley d at the base of the tower and over a pulley (Z to the drum [Z in the hull of the barge, which is operated by means of the engine located, for example, in the house E at the stern of thebarge. Means are provided for moving the tower backward and forward along the deck of the barge as follows: F is a shaft mounted on the deck of the barge. On this shaft are mounted four freely-moving spools. Two spools (Jr U carry the tower-moving ropes, and the spools H H carry ropes for warping the barge. These spools are all of the same size, and each is provided with a suitable clutch, whereby it may be connected to the shaft F to move with it, the shaft being suitably connected with the engine, as at F, so as to be reversible. The connection of the shaft with the engine is not shown in detail and need not be specifically described, as it may be an ordinary worm-andgear connection, nor need the clutches referred to be specifically described, as any of the ordinary clutches suitable for heavy work will answer. The purpose of these clutches is to place the various spools within easy control and reach of the engineer. A rope 9 runs from one end of the truck C, which carries the tower, around pulleys g g to the spool G.

From the other end of the truck C runs a.

rope g round pulleys g g to the spool G. The ropes in question are wound difierently upon the said spools, so that although the spools are rotated in one direction one spool will unwind While the other spool winds up its rope. Thus by rotating the shaft F in either direction and making the proper connections between the spools G and G with the shaft the location of the tower C can be changed ineither direction ,upon the barge.

The means for changing the location of the barge with relation to the steamer comprises two hawsers, one of which, it, is connected to acleat near the bow of the steamer, preferably on one of the lower decks, and runs round a guide-pulley it and pulleys 71 it to the spool H. The other hawser it, coming from near the stern of the steamer, runs .roundthe pulley b to the spool H. These hawsers are wound upon the spools H H in such manner that winding up the hawser upon one spool will unwind it from the other. spools G G H H- are all of the same diameter, so that. an absolutely uniform motion may be given both to the towerv and to the barge itself, and thus it may be seen that the tower may be warped toward the stern of the barge at the same time as the barge itself; is being warped toward the bow of the steamer-and at exactly the same rate, so that the tower will not. change its position with relation to the port-hole through which the bunkering is.

are used, so as to lead the hawsers in.the

proper direction.

An examlnation Wlll show the various possibilities of this invention and its value for. the

purposes for which it is constructed. The steamer and the barge being oncelocated alongside each other, the process of unloading from the bunkers ofv the barge begins in the usual manner until the particular bunker over which the tower is located is emptied. Thereupon the engineer, connecting the shaft F with the engine so that itwill turn in the proper direction, moves the tower and at the same time movest-he barge, the tower being moved in one direction and the barge in the. other at,

The four.

substantially the same speed, so that the tower will not change its relation to the steamers port. full bunker, the shaft F is disconnected from the engine and the operation of bunkering goes on until another adjustment is needed, owing to the emptying of the second bunker in the barge. If by this time the bunker on board the steamer is full, so that the entire apparatus must. be moved, this can be done by connecting the spools H H with the shaft F and without connecting the spools G G. The barge will thenbe moved to the next port- WVhen the tower has arrived over the hole and the bunkering continued. I have shown in the drawings and have described a simple mechanism forcarrying on this bunker.-

ing operation; but it is evident instead of placing the engine upon the barge which carries the tower. the engine maybe placed uponanother barge, the two barges being; lashed together, the various ropes and'hawsers being guided to the proper. spools by suitable pulleys, or the engine being located upon the wharf the barge carrying the trolley can be warped along the wharffrom one coal-pocket to another, carrying the tower bymeansof which it is being unloaded, the ropes in this case beingcarried to .the spools on the engine by suitable guidingmeans.

WVhile the tower-moving means may consist of two ropes each wound .on its own spool, as shown, a single rope may be used. In this case each end of the truck supporting the tower has an end of the rope attachedto it, the middle of the rope beingwou-nd around a single spool. The turning of the spool in one direction will wind up the rope on one side of the spool and release a correspondingamount of rope on the other side, thus changing the; position of the truck and tower. In like manner a single warping-hawser may, be used to operate the barge with relation tothesteamer, one end'of the hawserbeing attached to. the bow of the steamer and the other. end gtO the stern thereof. These modifications are not specifically shown in the drawings, as it=is believed they willbe fully understood from this description by those skilledintheart.

It will be understood fromthisdescription thatmy invention may be embodied in ayariety of ways.
